Compressor mah! The more rpm means more air con gas is circulated hence the air con is cooler.......lol
This makes it sound like the compressor in a turbocharger. :biggrin:

bro renesis, aircond condenser fan OK ? check gas pressure too.
Fan is okay. Blowing. Gas pressure din't check.

Many new makes do not have the water temp meter dy. blue then warm up disappear, by the time red color appears may be too late.....lol
If thermostat jammed like my previous case, then really hard to detect until it is too late.

Unlike home air con, compressor speed and fan speed in constant. In Car air con, the engine speed determine the compressor speed as well as traveling at a faster speed the condenser fan is aided by wind passing through the condenser, therefore with faster engine speed the air con is cooler....:driver:

Looks like this encourages me to rev the engine harder during hot afternoon. :rofl:

Normal lah.
Is weird that the revs still seems to climb up nicely but I just can't feel the pulling feeling from torque. Like torque is robbed off.

oh. i thought the blue led ring on the speedo is for eco or something. hahaha. coz it changes from green when drive slow to blue when drive normal. so far no red color. :hmmmm:

What emblem is yours? Ring? maybe for something else. The blue emblem for my forester is the water temp emblem....lol

surprisingly on the jazz got no difference. like the ac compressor doesnt exist. LOL. oh, the new 2016 jazz no water temp gauge on the meter. just outside temperature only. dunno can set that to water temp or not. :hmmmm:
Same with Suprima S.

some mix feeling about temperature gauge.
Some driver don event see it until aircond feel warm, only notice needle at highest point.
Happened to me as a big lesson to always peep the gauge once a while. :banghead:
my nissan x-gear also no gauge, if red mean stop the car.

I noticed that my Wira 4G15's air cond seems to drain a lot of power from my engine especially during hot afternoon. On night time, early morning or on cooler days even with air cond switched on and compressor kicking in, the power drain seems to be less obvious.

Like when the compressor is kicking in during hot afternoon time, I notice a reduction in torque where I feel that my revs will climb but the pulling feeling from torque is not there. When I switched the air cond off or when the compressor is not kicking in, I can feel the pulling feeling from torque again. Is this normal that the compressor will draw this much of power especially during hot days?
Actually aircond compressor got 2 types that is rotary and piston.
Wira compressor are piston type where it is normal for power lost when it start working since a burden to engine..
Day time your aircond thermostat read that you need a lot of cool air where it will work more compare to night time..
If you want to cut a bit of the power lost, the best way is to lighten your crank pulley or block the heat into engine..

Hi TS,

I guess its pretty norm for Mitsubishi engine, same applies for my 4G63T.
I also feel the same, loss of power.

the rotary compressor very hard to find these days for 4gx engine. Even halfcut ones are not that good. Recon compressor mostly are pistons type. I broke my rotary compressor previously and now i think i'm using the pistons type coz very damn sluggish if ac is on. :bawling:

Those lightened and dampened crank pulley?

Even for your powerful engine, you can still feel the power loss from air cond compressor?

Do these rotary compressor had any disadvantages compared to piston ones?
